Introduction:
White cubic crystal or powder. In moist air micro has the water absorbability, long precipitation free iodine and turns yellow, and trace iodate was formed. Light and moisture can accelerate the decomposition. 1 g soluble in 0.7 ml 22 ml water, 0.5 ml water, ethanol, 8 ml 51 ml boiling ethanol, anhydrous ethanol, 8 ml of methanol, 2 ml 7.5 ml of acetone, glycerin, about 2.5 ml ethylene glycol. Its aqueous solution was neutral or slightly alkaline, can dissolve iodine. Its solution also gradient in oxide yellow, can add a small amount of alkali to prevent. Relative density 3.12. Melting point is 680 ℃. The boiling point of 1330 ℃. Approximate lethal dose (rats, intravenous) 285 mg/kg. Widely used in volumetric analysis preparation in the titration solution by iodine volume method. Preparation "rider in the haploid breeding, improvement, MS white and medium such as RM. Stool test, etc. A photograph. Pharmaceutical.
